Have all mails put in a single mbox, pull them and hand to sendmail for delivery.

To get addresses accepted you can either add items to the /etc/aliases, or put 
things in /etc/mail/local_names. The alias solution is easier. You may have to 
allow forwarding of stuff sent over the loopback address, I haven't done this in 
several years and can't be sure.

Set up fetchmail to pull from a local mailbox you can preload, and verify that 
delivery occurs, then point fetchmail at the real mailbox. That reduces your 
chances of lost mail.
